如何在Visual Studio中使用RichTextBox使documents.docx只读？

Question

下面是我的代码，当它调试时，文档将在Rich TextBox中打开，但它可以编辑，因此我需要它为ReadOnly。你能帮我解决吗？

void ImportWord() 
{ 
    Microsoft.Office.Interop.Word.Application wordObject = new Microsoft.Office.Interop.Word.Application(); 
    object File = @"C:\Users\czu_ecu\Desktop\OAG-WORK\Management_Letter_Template1.docx" ; //this is the path 
    object nullobject = System.Reflection.Missing.Value; Microsoft.Office.Interop.Word.Application wordobject = new Microsoft.Office.Interop.Word.Application(); 
    wordobject.DisplayAlerts = Microsoft.Office.Interop.Word.WdAlertLevel.wdAlertsNone; Microsoft.Office.Interop.Word._Document docs = wordObject.Documents.Open(ref File, ref nullobject, ref nullobject, ref nullobject, ref nullobject, ref nullobject, ref nullobject, ref nullobject, ref nullobject, ref nullobject, ref nullobject, ref nullobject, ref nullobject, ref nullobject, ref nullobject, ref nullobject); docs.ActiveWindow.Selection.WholeStory(); 
    docs.ActiveWindow.Selection.Copy(); 
    this.richTextBox2.Paste(); 
    docs.Close(ref nullobject, ref nullobject, ref nullobject); 
    wordobject.Quit(ref nullobject,ref nullobject, ref nullobject); 
} 

private void btnTemML_Click(object sender, EventArgs e) //Handles the actions of the template button 
{ 
    btnAdd_Finding.Visible = false; 
    listView2.Visible = false; 
    label8.Visible = false; 
    richTextBox1.Visible = false; 
    listView1.Visible = false; 
    listView3.Visible = false; 
    richTextBox2.Visible = true; 

    ImportWord(); 

    listView1.Items.Clear(); 
}

您可以尝试下面的代码。

richTextBox2.Visible = true; 
richTextBox2.IsReadOnly = true;
